If we are not able to publish our own device list, we just ignored it.
This commit will show at least an error message and informs the user that this
device is currently not in the list of devices.
See Issue: #1538
Next task will be to handle the <precondition-not-met/> conflict properly.
The most loggings has been set to debug. Just in case of error / problem the
logging should be done with log-level ERROR or WARNING.
We will see later, which loggings should be switched to log-level INFO.
This improvement has been done to find OMEMO bugs.
See also: #1070#1530#1538
If the message (key) can't be encrypted for any device, sending the
message is refused and an informative error message is presented to the
user.
Also, don't encrypt for the same device, since the OMEMO XEP disallows
this.
In 0.9.x we fixed an issue, because OMEMO devices should be defined in "item"
with id "current". This should work, but it won't work if there is no "current".
If there is no "current" we will just use the first item.
Issue #1384
Profanity requests the device list and keys for contacts, also when the user
hasn't generated the OMEMO key. If the user has no OMEMO key, there is no need
to request OMEMO information.
Issue: #1332
We call omemo_init() when starting profanity and should have an
omemo_close() at exit.
For now we free the fingerprint autocompleter in there.
Fixes valgrind:

This is actually not needed because result will always be set.
hartmann had problems building profanity on OpenBSD and he proposed this
patch.
Let's use it to make the compiler happy there.
